I am noticing bleed over when pulling differential data from channels.
here is an output: where 0 is channel 0,1 channel 1 is 1,2 and so forth..
Channel 0: 1.718778v
Channel 1: 0.068488v <--- where is this coming from?
Channel 2: 0.000106v
Channel 3: 0.000100v
The only channels with anything hooked up to them are Channels 0 and 1 with a Load Cell (4 wire Wheatstone) (run through an OpAmp) where Channel 0 has the Vout and Channel 1 is the VRef coming off the OpAmp
the OpAmp and the Load Cell do share the same 5v+ and VCC. The sample rate is 30k (really only getting about 4000 samples/second) and the Gain is set to 4.
Happy to share code too if there is value to it.. I can't tell if the bleed is timing or electrical given that it runs all zeros (or very near zero) when there is no weight.
